I think that it would be helpful to include the KAC ID in a description of the ban on http://kigenac.com/bancheck.php. This way people cant pull, "I don't know why I was banned," excuse because it will give you the reason right there.

Also making a direct link to the ban list checker on the homepage will cut back on a lot of the protests that end in,

Checking 'STEAM_0xxxxxxxx'...
Steam ID is NOT banned.

Your ban is a local server ban & not on the KAC global ban list.
Please contact the local server provider.

That is entirely up to Kigen to decide if he wishes to share that information.
Even I do not have access to this data.
Until such time as this changes, you will need to be patient and wait for his reply.

I have been specifically instructed to reply in this manner on protest.
